- When scaling down a ReplicaSet, delete doubled up replicas first, where a "doubled up replica" is defined as one that is on the same node as an active replica belonging to a related ReplicaSet.  ReplicaSets are considered "related" if they have a common controller (typically a Deployment). ([#80004](https://github.com/kubernetes/kubernetes/pull/80004), [@Miciah](https://github.com/Miciah))

of adding _cgo_import.go to the package, the go tool adds an empty
file named dynimportfail. The _cgo_import.go file is only needed when

named dynimportfail it reports an error if it has been told to use
internal linking mode. This approach is taken because generating
